In addition, a cover 2 is hinged to the upper side of the housing 1 to be openable and closable, and the cover 2 is located at the upper side to facilitate the exchange of the roll film 3.

The container sealing and packing machine 100 of the present invention, which is composed of the fixing driving means 10, the elevation starting means 20, the heater device 30 and the spherical tray 40, will be described in more detail.

First, as shown in fig. 2 to 4, the fixing driving means 10 is a structure for performing a heat-melting and cutting process on the film 3 supplied to the container 4 by the ascending and descending movement of the heater device 30 provided on the ascending and descending actuating means 20, and then completing the sealing and packaging of the container 4, and comprises the following structures: a mounting bracket 11 fixedly mounted inside the cabinet 1 by a general bracket; the power unit 10a is attached by a fixing bracket 12.

Here, the mounting brackets 11 are preferably connected to and support the elevation actuating means 20 at both sides, and are formed as a pair to guide the front and rear stable movement of the spherical tray 40, and are fixedly mounted at both sides of the inside of the cabinet 1, respectively; the fixing brackets 12 are preferably connected to the front and rear sides of the mounting brackets 11, respectively, for stable connection and firm support of the pair of mounting brackets 11.

The power unit 10a is connected to the fixed frame 12 and moves the elevation actuating means 20 up and down by the driving force of the turning motor 15, and various methods can be applied as long as the power unit converts the rotational motion generated by the driving of the turning motor 15 into linear motion and then moves the elevation actuating means 20 up and down, as in the case of the coupling method using a rack, a worm gear, and a bevel gear.

In order to make the present invention simpler, the power unit 10a may be eccentrically rotated about the turning shaft 13 by driving the turning motor 15, and the elevation actuating means 20 may be moved down by the eccentric rotating portion 17, and in this case, an elastic member 26 for returning the elevation actuating means 20 to its original state should be further included.

Therefore, the tension of the belt 145 can be adjusted by the pulley 14 having the above-described structure, and in the sealed package of the container 4, not only the erroneous activation due to the incomplete eccentric rotation of the eccentric cam 16 can be prevented, but also the maintenance of the belt 145 can be facilitated, and in this case, any structure may be used as long as the adjustment pulley 143 is rotated after the adjustment opening 144 is fixedly mounted in a state of being rotated about the axis.

Secondly, as shown in fig. 2, 3 or 5, the elevation starting means 20 is configured to receive the guide of the plurality of elevation bars 21 by the driving force of the power device 10a to start elevation so that the heater device 30 completes the sealed packing of the container 4, and the plurality of elevation bars 21 slidably coupled in the vertical direction are formed on the mounting bracket 11 to perform the elevation action by the driving force of the power device 10a, and is characterized by comprising the elevation bars 21, the elevation plate 25 and the fixing member 27.

First, the up-down rod 21 is slidably coupled to the mounting bracket 11 in the up-down direction by a known normal bush, a bearing, or the like, and is configured to guide the up-down movement of the up-down starting means 20 in a stable manner, and for this reason, it is preferable that 4 pieces of the up-down rod 21 are coupled to the mounting bracket 11 after being separated in the front-rear direction, the left-right direction, and the like.

The lifting plate 25 is configured to be lifted and lowered after being coupled to the lifting rod 21, and is composed of a first lifting plate 22 which is lifted and lowered in the vertical direction by being driven and started by the power unit 10a configured in the fixed driving means 10 after being coupled to the lower end of the lifting rod 21; a second lifting plate 24 linked with the first lifting plate 22 after the upper end of the lifting rod 21 is combined; the second elevating plates 24 are formed as a pair for mounting the heater device 30, and are coupled to the upper ends of the elevating rods 21 and arranged to face each other so as to be symmetrical with each other in the left-right direction.

Further, the fixing member 27 is a structure provided in the second elevation plate 24 for the purpose of fixed mounting of the heater apparatus 30, and includes the following structures: support brackets 271 formed on the inner surfaces of the pair of second elevating plates 24 so as to support the heater device 30; and a fixing bracket 272 which is coupled to the upper portion of the second elevating plate 24 by a normal bolt coupling or the like, and then fixes the heater device 30 inserted into the supporting bracket 271.

Further, in order to facilitate the fixing of the heater device 30 in the fixing member 27, it is preferable that a guide 273 coupled to the upper portion of the second elevating plate 24 is further included, and in order to facilitate the separation of the heater device 30 without the release of the coupling of the fixing frame 272, it is preferable that the support stand 271 is provided at the inner middle portion of the second elevating plate 24, that is, at only a portion of the inner side of the second elevating plate 24.

In addition, as described above, in order to make the structure compact by the simple structure of the present invention, it is preferable that the power unit 10a for lifting the lifting starting means 20 further includes the eccentric rotation portion 17, and according to this structure, the lifting starting means 20 is composed of the lifting lever 21, the lifting plate 25, the elastic member 26 and the fixing member 27, which performs the lifting action by the pressing force when the eccentric rotation portion 17 eccentrically rotates and the elastic force of the elastic member 26.

First, the elevation rod 21 is configured to be slidably coupled to the mounting bracket 11 in the vertical direction by a known normal bush, a bearing, or the like, and is configured to stably guide the elevation movement of the elevation activating means 20, and for this reason, it is preferable that four elevation rods 21 are coupled to the mounting bracket 11 after being separated in the front-rear direction and the left-right direction.

In addition, the lifting plate 25 is a structure that starts lifting after being combined in the lifting rod 21, and is composed of the following structures: a first lifting plate 22 which is driven to descend after the lower end of the lifting rod 21 is connected and the eccentric rotation of the eccentric rotating part 17 formed in the fixed driving means 10, that is, after the eccentric rotation of the eccentric cam 16 is pressed; and a second lifting plate 24 which is coupled to the upper end of the lifting rod 21 and then is interlocked with the first lifting plate 22.

At the same time, a roller bearing 23 is provided in the center of the first lifting plate 22 in contact with the eccentric cam 16 of the eccentric rotating portion 17, and is rotatably attached to the eccentric cam 16 by means of a bolt connection or the like, so that the lifting movement of the lifting actuating means 20 is facilitated.

The second elevating plates 24 are formed in a pair for mounting the heater device 30, and are coupled to and arranged opposite to each other at the upper end of the elevating rod 21 so as to be symmetrical with each other in the left-right direction.

The elastic member 26 is configured to return to an initial state by moving the elevation activating means 20 activated by the eccentric rotation portion 17, that is, by lowering the eccentric cam 16, upward by an elastic force, and is provided between the mounting bracket 11 and the second elevation plate 24 in a state of being inserted into each of the four elevation rods 21, and may be configured by a well-known normal spring.

Thirdly, as shown in fig. 2, 3 or 5 to 9, the heater device 30 is installed on the upper portion of the elevation starting means 20 in such a manner as to be interlocked with the elevation starting means 20, and performs a fusing and cutting process of the film 3 supplied to the container 4, and is composed of a heater part 31 which performs the fusing and cutting process and a support frame 32 which elastically supports the heater part 31.

First, as before, the heater section 31 is composed of the following structure: a normal heater panel 311; the heater portion 31 is a conventionally known structure and is formed on the outer side of the heater panel 311, and a cutting blade 312 for cutting the film 3 is formed to be aligned with the opening outer edge portion of the container 4, and a detailed description thereof is omitted.

As described above, the support frame 32 is fixedly attached to the upper portion of the elevation actuating means 20 by the fixing member 27, and elastically supports the heater unit 31, and hanging brackets 321 to be inserted into the support brackets 271 of the fixing member 27 are formed on both side surfaces for fixing.

Meanwhile, between the heater part 31 and the support frame 32, a plurality of elastic support parts 33 are provided at equal intervals in order to elastically support the heater part 31 by the support frame 32, and each elastic support part 33 is composed of a bushing 331, a support bolt 332, and a spring 333.

Here, the bush 331 is slidably coupled to the heater part 31 in the vertical direction, and has a head portion formed on the outer side of the upper end thereof to prevent the bush 331 from being completely inserted into the heater part 31, and a hollow portion formed therein for inserting the support bolt 332.

As described above, the stay bolt 332 is inserted into the bush 331, and the end thereof is bolted to the corner of the heater part 31, and the heater part 31 and the stay frame 32 are connected and mounted, and the spring 333 is inserted into the outer diameter of the bush 331 and is disposed between the heater part 31 and the stay frame 32, and then the container 4 is sealed and packed, thereby performing a buffer function.

Therefore, when the film 3 supplied to the container 4 is subjected to the heat-melting process by the heater device 30 lowered in conjunction with the elevation actuating means 20, the heater portion 31 receives the guide of the elastic support portion 33 to perform the cushioning effect, and the cutting process of the film 3 is performed by the cutting blade 312, thereby performing the safe seal packaging of the container 4.

Fourth, as shown in fig. 1 and 2 or fig. 7 to 9, the spherical tray 40 is a working means for lowering the accommodated container 4 and inserting the same into the inside of the present invention, and constitutes a jig panel 41 for accommodating the container 4 and having a container accommodating hole.

The structure of the spherical tray 40 having the elevation driving means 43 is the same as the structure of the conventional spherical tray 40 in which the container base plate 42 capable of supporting the lower part of the container 4 is separately installed on the lower side of the jig panel 41, the container base plate 42 is connected to the normal elevation driving means 43 such as a ball screw which rotates according to the driving of the motor, and the spherical tray 40 is automatically elevated when it enters, i.e., moves forward and backward.

The ball tray 40 is inserted, that is, moved forward and backward, on both sides of the ball tray 40, and is slidably coupled in the forward and backward directions by the mounting bracket 11 provided on the fixed driving means 10.

For this purpose, a plurality of rollers 19 should be provided on the inner side surface of the mounting bracket 11 constructed in the fixed driving means 10, and a guide rail connected with the rollers 19 should be basically provided on the side surface of the spherical tray 40, however, the present invention is characterized in that an annular groove 18 is further provided on the outer peripheral surface of the rollers 19, and protrusions 48 inserted into the annular groove 18 on the outer peripheral surface of the rollers 19 are respectively provided on the upper and lower sides of the guide rail 49, that is, a structure is formed long in the front-rear direction, thereby preventing the rocking phenomenon when the spherical tray 40 moves forward and backward.

Accordingly, when the spherical tray 40 for accommodating the containers 4 is inserted, the arrangement, i.e., the left and right positions, of the containers 4 is always accurate, and the occurrence of the defective sealed package due to the incorrect arrangement of the containers 4 can be effectively prevented, which is also an advantage of the present invention.

The preferred configuration of the present invention described above functions as follows:

first, the container 4 is inserted into the container receiving hole formed in the jig panel 41 of the spherical tray 40, and after the container 4 is fixed to the container pad 42, the spherical tray 40 is pushed in, that is, moved backward.

Then, in the course of the spherical tray 40 entering, the container base plate 42 is lowered and started by the driving of the elevating driving means 43, the container 4 placed on the container base plate 42 is completely inserted into the container receiving hole, and thereafter, the arrangement of the container 4 is completed by the complete backward movement of the spherical tray 40, and at this time, the spherical tray 40 enters in a state that the guide rail 49 convex portions 48 formed on both side surfaces thereof are inserted into the roller 19 grooves 18 formed on the mounting bracket 11 of the fixed driving means 10, and the spherical tray 40 stably enters without the left-right shaking phenomenon, whereby the container 4 received in the spherical tray 40 can be placed at an accurate position.

Thereafter, the film 3 supplied to the container 4 is subjected to a heat-melting and cutting process, thereby completing the sealed package of the container 4.

The sealing packing of the container 4 is completed when the eccentric cam 16 of the eccentric rotation portion 17 formed on the fixed driving means 10 eccentrically rotates in accordance with the driving of the rotary motor 15, and the sealing packing of the container 4 is started by the eccentric rotation of the eccentric cam 16 formed on the eccentric rotation portion 17, which will be described in more detail below.

When the rotary motor 15 configured on the fixed driving means 10 is driven, the reverse shaft 13 receiving the power transmission of the rotary motor 15 through the pulley 14 rotates, and thereby the eccentric cam 16 connected to the reverse shaft 13 rotates eccentrically, and the elevation starting means 20 attached to the lower side is elevated and started.

That is, if the eccentric cam 16 is eccentrically rotated and one side of the eccentric cam 16 is eccentrically protruded in the lower direction, the roller bearing 23 of the elevation startup means 20 attached to the eccentric cam 16 is interlocked therewith, and at this time, the rotation is started, so that the operation of softly guiding the lowering startup of the elevation startup means 20 is performed.

Further, the lowering operation of the elevation actuating means 20 is stably guided by the four elevation rods 21 slidably coupled to the mounting bracket 11 of the fixed driving means 10, and the heater device 30 fixedly mounted on the elevation actuating means 20 is moved only in the vertical direction without shaking back and forth, whereby the heater device 30 and the container 4 for supplying the thin film 3 are accurately aligned.

Therefore, after the above process, the film supplied to the container 4 is heat-melted and cut by the heater device 30, thereby completing the sealed packing of the container 4, and in the present invention, since the eccentric rotation force of one eccentric cam 16 is stably vertically moved by the four elevating rods 21, that is, the vibration phenomenon of the heater device 30 can be prevented, the error and the false start phenomenon do not occur in the sealed packing of the container 4.

After the sealing packing of the container 4 is completed, the force for pressing the elevation starting means 20 downward is removed by the continuous eccentric rotation of the eccentric cam 16, and at this time, the elevation starting means 20 is lifted by the elastic force of the elastic member 26 provided between the mounting bracket 11 and the second elevation plate 24 of the elevation plate 25 in a state of being inserted into the elevation rods 21, respectively, so that the elevation starting means 20 is easily returned to the initial state, and thus, the uniform sealing packing of the container 4 can be repeatedly performed.

Further, when the heater device 30 needs to be replaced or maintained, the heater device 30 inserted and fixed between the support holder 271 of the fixing member 27 and the fixing frame 272 is moved in a sliding manner by applying a force in the rear direction, and the front side of the heater device 30 is slightly lifted and tilted, and the heater device 30 can be easily disassembled only by taking out the heater device 30 by the operation of removing the heater device from the fixing frame 272 without detaching the fixing frame 272 for fixing the heater device 30, and when the heater device 30 is remounted, the heater device 30 is inserted between the support holder 271 of the fixing member 27 and the fixing frame 272) and then the heater device 30 is applied a force in the direction of the guide frame 273, and the heater device 30 can be attached to the guide frame 273 only by moving the heater device in a sliding manner, whereby the heater device 30 can be easily fixed and installed.

Therefore, when the heater device 30 needs to be replaced or repaired, the maintenance is facilitated, and the management is easy.
